Application July 9, 1934, Serial No. 134,391
this application is a trailer of the'three-point suspension type designed for pivotal connection to the rear end of a power propelled road vehicle, and provided with practically all the conveniences of a home. 7 The main object ofthe invention is to provide a trailer of small weight and sturdy construction, and adapted for connection to the power car so as to have practically no eilect on the speed thereof. v
Another object of the invention is to provide a trailer in which a drop floor is employed throughout the greater part thereof to enable persons of average height to move about the interior thereof without bending.
A further object of the invention resides in the provision of shock absorbing mechanism for connecting the trailer pivotally to the. power car,
whereby the inertia shocks of the trailer caused by the stopping-or starting of the power car are greatly reduced or eliminated.
Another object of the invention resides in the provision of an air-cushioned rubber block as a substitute for the usual leaf springs supporting a vehicle body on the wheels thereof.
Other objects of the invention will become apparent as the detailed description thereof proceeds. 1
In the drawings:
Figure 1 is a perspective view of the trailer embodying the present invention as applied to the rear end of a propelling automobile;
Figure 2 is a fragmentary side elevation of one of the spring supports for chassis of the trailer; Figure 2-a is a part side elevation and part longitudinal section of an air cushioned rubber block, used in place of the ordinary vehicle springs;
Figure 2-?) is a section taken on line 2b-2b of Figure 2a;
Figure 3 is a diagrammatic layout in plan of the trailer, illustrating the arrangement of the the Present invention is of the three-point suspension type in which the front end is pivotally connected. to any suitable fixture at the rear end of a power car. The coach or body of the trailer is supported on framework which includes box sills I and 2 constructed to receive the axle 3 which supports the wheels W of the trailer. These box sills are spaced widely apart at their rear end and gradually converge toward in the front end of the trailer, sufliciently to form a support for a full length bed 4. The foremost ends of the sills I and 2 support the platform with its framing converging in the direction of the pivotal connection 5 between the trailer and a bracket 6 suitably secured to the rear end of the chassis of the power car.
The sills l and 2 comprise the converging vertical walls I and 8 of the sunken structure sethe springs H and I2, having their outer ends connected by the usual spring shackles to the bottom side of the horizontal side platforms II and I4 forming the mezzanine floor and suitably secured -to the outside walls of the box sills, re-
spectively. Slots [5 and IS in the platforms I3 r and 14 receive the upper'parts of the wheels W; and casings l5 and" ii are constructed on said platforms to receive said parts.
The axles is enclosecl'by a transverse casing having vertical walls i1 and I8 (see Figures 3 and 5) extending as braces between said box sill, vertical walls 1 and 8.
At their front end, the side walls I and; 8 are braced apart by transverse struts 3 and 34; and, have secured to their outer end a triangular draw-bar frame, designated generally by the reference character 35 and slidably' supporting a draw-bar 35 having a coupling hook ll formed on one end thereof.
The chassis of the trailer may be secured by the usual leaf spring arrangement shown in Figure 2 of the drawings. In order to reduce the weight and cost and eliminate squeaks as much as possible, I prefer to use the air cushioned rubber block construction shown in Figures 2a and 2-D of the drawings. Each of these blocks comprises a metal box I 43 provided with lugs I44 adapted to be bolted or otherwise secured to the outside of the vertical walls of the sills. A rubber block I45 having a substantially elliptical aperture I46 extending therethrough is suitably secured in the box I 43, as by the inturned flanges I41 and I48 shown'in Figure 2-1) of the draw ings. The curved edge of elliptical aperture I48 is made convex in cross section to receive the concave groove I4'l of a metal shoe I48 which is provided with an aperture I49 forming a bearing for the axle 3. The rubber block I45 is provided with radiating bores to enhance the resilience of the material in the block. 1
By the air cushion block just described, the bouncing of the body on the axle will be eased considerably. The harder the bounce the tighter the holes will seal themselves against the box plate supports and the axle shoes, thus giving the effect of air cushion rubber pads. The shoe on the axle and the box on its chassis are edged to compact the rubber on the pressure bounce. The top portion should be somewhat greater than the bottom portion, for the sake of the load; and
the lower portion of the cushion is intended to check the rebounce. The flaring edges allow the same to hold the axlein proper alignment; still with this cushion there is ample freedom to take care of unevenness in rough road shocks.
What I claim is:
1. In an auto trailer, a pair of wheels connected by an axle, a frame having a part arranged between said wheels and supported thereby, said frame including sills through which the opposite ends of said axle extend, and a drop floor secured to the lower edges of said sills on secured to the lower edges of said sills on opposite ends of and below said axle, and a casing for saidaxle within said frame and supported by the drop floor to form a seat or step.
3. In an. auto trailer, a pair of wheels con- 4 nected by an axle, a frame having apart arranged between said wheels and supported thereby, said frame including sills through which the opposite ends of said axle extend, a drop floor supported by the lower edges of said sills on opposite ends of and below said axle, a casing for said axle within said frame and supported by the said sills and projecting from the drop floor to form a seat or. step, platforms extending along opposite sides of said frame and supported by the upper edges of said sills, the upper parts ofsecured to the lower edge of said sills on opposite ends of and below said axle, a casing for said axle supported by the drop floor to form a seat, supporting platforms secured to and supported by the upper edges of said sills, and a closed body supported by said platforms.
5. In a vehicle, the combination of a body frame and axle, boxes-secured to said frame and surrounding the opposite ends of saidv axle, cushions of resilient material secured in said boxes and provided with elliptical apertures within which the endsof said axle are centered, the walls of said apertures being convex, elliptical metallic shoes within said apertures and having concave walls closely fitting the convex walls of said cushions, the opposite ends of said axle being supported by the convex inner walls of said shoes.
6. In avehicle, the combination of a body frame and axle, boxes secured to said frame and surrounding the opposite ends of said axle, cushions of resilient material secured in said boxes and provided with elliptical apertures within which the ends of said axle are centered, the walls'of said apertures being convex, elliptical metallic shoes within said apertures and having concave walls closely fitting the convex walls of said cushions, the opposite ends of said axle being supported by the convex inner walls of said shoes, said cushions being provided with air receiving boxes extending normal to the elliptical apertures thereof.
